Ho un portatile "HP-255g5" sul quale è installato Ubuntu 22.04 con ambiente grafico XFCE. Tutto funziona egregiamente, se non fosse per un piccolo ma fastidioso problema. Per impostazione del power-manager quando chiudo il portatile il sistema va in sospensione. Quando però lo riapro, tuttavia, e dopo aver messo correttamente le credenziali nel login, lo schermo diviene improvvisamente diventa completamente nero, sebbene in sottofondo si senta ancora del suono della canzone precedentemente in esecuzione. Ecco alcuni comandi utili:
